Deputies responding to a call for assistance in San Carlos Park Sunday found five people dead, including three children ranging in age from 2 to 10 years old.
The Lee County Sheriff's Office received the 911 call from the residence at 17372 Phlox Drive at 2:25 a.m.
The scene remains held as crime scene technicians collect and document evidence, officials said in a release issued Sunday night.
The remains will be taken to the District 21 Medical Examiner's for autopsies.
The identities of the decedents are being withheld pending the next of kin notification.
"At this time, it is our belief this is an isolated domestic incident and there are no immediate concerns for the community," the release states.
The investigation is ongoing. No other information was released.
